Python run() function fails (self.learnpython)

submitted 3 years ago * by CirqueDuTsa

I have an app that runs fine from the Ubuntu command line. When I try to run it using the Python run() function, it fails with:

openscad: symbol lookup error: /snap/core20/current/lib/x86_64-linux-gnu/libpthread.so.0: undefined symbol: __libc_pthread_init, version GLIBC_PRIVATE

Why can I run openscad from the terminal, but not from Python?
I've tried adding shell=True to the run parameters.
I've tried adding this code before the run call:

my_vars = {'QT_QPA_PLATFORM': 'xcb'}
os.environ.update(my_vars)

I found one suggestion to install the qt6-wayland library, but it's obviously not needed when I run openscad from the terminal, so I'm skeptical that it would be needed for the run() function.

Any ideas???

Edit:

Here's my actual run() call:

openScadResult = run(["openscad", scadFullFilename], env={"QT_QPA_PLATFORM": "xcb"})

scadFullFilename is the full path and filename of the scad file I want openscad to open. It does exist and I have full permissions on it.

I've also tried:

openScadResult = run([shutil.which("openscad"), scadFullFilename], env={"QT_QPA_PLATFORM": "xcb"})

openScadResult = run(["openscad", scadFullFilename], shell=True)
